Description.

As seen in the accompanying drawings, the thread A is delivered fromsuitable spools over a rest bar or receiving member 8 of theherein-described carriage. The carriage consists of a skeleton framehaving sides 9 spaced apart in parallel relation. The sides 9 arestructurally united by crossbraces 10 and by tie rods 11 and 12. Therods 11 and 12, as shown best in Figs. 2 and 3 of the drawings, are eachprovided with a screw-thread operatively engaged by clamping nuts, 13and 14, respectively, between which are clamped in service, reed-holders15 and fingers 16, respectively. Both of these are laterally adjustablein opposite dil'GCtlOIlS: from each other. Said tie-rods are furtherprovided with clamping nuts 17,

e which clamp rigidly the sides 9 to hold the same-in structuralrelation.

The thread A travels "over the carriage in the direction shown by thearrow a in Fig. 1' of the drawings. During its travel it is supported bythe glass spreader bars 18 and 19, and rollers 20 and 21, the roller 21being the delivering member of the device. Between the bars 18 and 19,the alternate threads are separated, one set of said threads passingbelow the bar 18 and above the bar 19, and the other set of threadspassing above the bar 18 and below the bar 19. As shown best in Fig. 1of the drawings, this forms what is known in the art as a cross. Thecross is employed as the most efiiolent means for properly spacing thethreads 1n their passage through the carriage for delivery over theroller 21 thereof.

It is found desirable in feeding the thread A to the reel from which itis re-wound to the loom drum, that .the width of the sections deliveredby each operation of the carriage to the reel should have apredetermined compactness, and, further, that the edges of the sectionsbeing delivered should be prevented from thinning out, which wouldproduce in the woven material what is known in the art as shiners. It isto prevent this that I use the guide fingers 16.

The fingers 16 are held on the tie rod 12 between the clamping nuts 14,said nuts frictionally engaging the end of the fingers with sufiicientforce to prevent them being dragged by the thread A out of their uprightactive position. the nuts 14 is not sufficient, however, to prevent thetilting of the fingers 16 so that the ends thereof may be disposed belowthe plane of the thread A. This forms a convenient means for replacingany stray thread The engagement of i with a spread wider than the spacebetween the fingers 16, which governs the delivery of the section of thethread being transferred to the reel. j 7

As seen best in Fig. 2 of the drawings, the

holders may be spread to accommodate reeds of different widths. To thisend they are adjustable to'the proper places by simply running theadjacent nuts over, slidi the holders to the new position and againtightening the nuts. These reeds are of conventional construction andare produced in commerce to difi'erent widths. Heretofore thepractice'has been to provide a carriage with a reed of maximum widthandwhen the section has been reduced, the center of the reed I alone hasbeen employed. As a result of this practice, the center of the reed hashad constant wear while the lateral portions have had relatively littlewear. Consequently, the center of the reed is worn awaynecessitat- I ingthe abandonment of the whole reed. This has proved of considerable lossto manufacturers. I

In the resent invention, where the holders 15 are a justa'ble andvariable in their relative separation, a reed of a width correspondmgwith the width of the section may be employed.- The result of thispractice is that the reeds are worn evenly throughout their spread. Asshown by the dotted lines in Fig. 1 of the drawings, the holders 15 andreed 22 carried'thereby may be rocked on the rod 11 to positions whichfacilitate the operations of crossing and knotting the threads.

By carrying the thread A in the-present invention above the rollers 20and 21, the same is made accessible for manipulation by the operator. Italso serves an additional and valued purpose in quickly detecting anybroken threads which may result from the operation of the warpingmachinery. Also, any adhesion which would result in the twisting isquickly detected and readily corrected.
